followable_type「ApplicationRecord」，而不是RoR中的應用「用戶」

Question

在我的項目我使用acts_as_follower寶石，以實現用戶

所以在我的User類中的後續/未追蹤功能，我有

class User < ApplicationRecord 
    ... 
    acts_as_follower 
    acts_as_followable 
    ... 
end 

但在db表Follow，該follower_type是User（這是正確的），而followable_type是ApplicationRecord

我是，如果你非常感謝可以幫助我瞭解爲什麼，在此先感謝..

的一些信息：

follows_controller.rb：

class FollowsController < ApplicationController 

def create 
    @user = User.find(params[:id]) 
    if(current_user!=@user) 
     current_user.follow(@user) 
     redirect_to users_show_path(:id => @user.id) 
     flash[:notice] = "You are now following #{@user.username}." 
    end 
end 

def destroy 
    @user = User.find(params[:id]) 
    if(current_user.id!=@user.id) 
     current_user.stop_following(@user) 
     redirect_to users_show_path(:id => @user.id) 
     flash[:notice] = "You are no longer following #{@user.username}." 
    end 
end 
end 

schema.rb：

create_table "follows", force: :cascade do |t| 
    t.string "followable_type" 
    t.integer "followable_id",     null: false 
    t.string "follower_type" 
    t.integer "follower_id",      null: false 
    t.boolean "blocked",   default: false, null: false 
    t.datetime "created_at" 
    t.datetime "updated_at" 
    t.index ["followable_id", "followable_type"], name: "fk_followables" 
    t.index ["follower_id", "follower_type"], name: "fk_follows" 
end 

follow.rb

class Follow < ActiveRecord::Base 

    extend ActsAsFollower::FollowerLib 
    extend ActsAsFollower::FollowScopes 

    # NOTE: Follows belong to the "followable" interface, and also to followers 
    belongs_to :followable, :polymorphic => true 
    belongs_to :follower, :polymorphic => true 

    def block! 
    self.update_attribute(:blocked, true) 
    end 

end

因爲我請參閱gem description，只有主分支支持Rails 5，可能是這個原因。

所以你需要在你的Gemfile，更換

gem "acts_as_follower" 

通過

gem 'acts_as_follower', github: 'tcocca/acts_as_follower', branch: 'master'
